A vehicle may be understood to be a manually operated vehicle, for example by a driver, and / or a partially, fully or fully automated vehicle. Furthermore, under one
Fahrzeug ein PKW und/oder ein LKW und/oder zweirädrige Fahrzeuge und/oder andere Fahrzeuge, wie beispielsweise Landmaschinen und/oder Arbeitsmaschinen (Bagger, etc.) verstanden werden. Unter einer Fahrstrategie der wenigstens zwei Fahrzeuge ist beispielsweise eine Vorgabe zu verstehen, welche einen vorgegeben Mindest- und/oder Maximalabstand zwischen den wenigstens zwei Fahrzeugen umfasst. Weiterhin umfasst die Vorgabe zusätzlich oder alternativ eine vorgegebene Mindest- und/oder Maximalgeschwindigkeit für die wenigstens zwei Fahrzeuge, wobei die Fahrstrategie für jedes der wenigstens zwei Fahrzeuge, beispielsweise abhängig von dem wenigstens einen Umgebungsmerkmal eine eigene Geschwindigkeits- und/oder Abstandsvorgabe - relativ zu dem Vehicle a car and / or a truck and / or two-wheeled vehicles and / or other vehicles, such as agricultural machinery and / or work machines (excavators, etc.) are understood.
